If you’re looking for the best online brokers to help you buy and sell stocks, the good news is that there are really no bad options. At least, that’s what the latest American Customer Satisfaction Index scores say about major Internet stockbrokers.

Three big names share the top spot on the 2011 list of the best online brokers for customer satisfaction. According to the latest ACSI report, Charles Schwab (NYSE:SCHW), E*Trade Financial (NASDAQ:ETFC) and Fidelity all tie for the top spot for the best online brokers.

Specifically, these three online brokers rated a 79. Close behind was TDAmeritrade (NASDAQ:AMTD) at 78, with all others taking up the rear with a customer satisfaction score of 75 for the 2011 reporting period.

The average for the online brokers industry was 76.

The scores for top brokerages remained largely unchanged, though E*Trade did see a significant rise from 76 to 79 compared with last year. Schwab slipped slightly from 80 to 79, but otherwise none of the major groups saw a decline in their score.

Click to EnlargeThe drag on the sector actually comes from “all others,” which stumbled the most – from 78 to 75. That skewed the overall industry satisfaction from 78 down to 76 for online brokers in 2011.

Internet brokerage businesses as a whole were pretty middle of the road when it comes to satisfying customers. The worst industry group as measured by the annual ASCI report were the major airline operators with a score of 65, and the best were credit unions with 87.
